'UNITF STATES PATENT OFFICE ROY D. KING, OF CHICAGO, ILLINOIS, ASSIGNOROF ONE-HALF TO JOI-IN NELSON, 0F CHICAGO, ILLINOIS.

HINGE.

To aZZ whom it may concern."

Be it known that I, Ror D. KING, a citizen of the United States,residing at Chicago, in ythe county of Cook and State of Illinois, haveinvented a new and useful Improvement in Hinges, of which the followingis a specification.

This invention pertains particularly to spring hinges, and moreespecially to hinges adapted for use in connection with screen doors.

The primary object of my invention is to provide a hinge o'f improvedand simplified construction, the leaves of which may be readilydisconnected from each other to enable the removal of the door to beeffected.

The invention is illustrated in its preferred embodiment in theaccompanying drawing, in which- Figure l represents a front elevationalview of the improved hinge; Fig. 2, a side elevational view of the same;Fig. 3, a section taken as indicated at line 3 of Fig. 2; Fig. el, atransverse section taken as indicated at line e of Fig. l, and Fig. 5,an inner View of a spring-adjusting barrel employed.

rlhe improved hinge comprises leaves A, A; a removable pintle orconnecting-pm A2; a spring A3; and a spring-adjusting barrel A4.

The leaf A is provided with end-flanges l and a spring-housing or barrel2. The housing 2 is cut away at its upper end to accommodate therevoluble spring-adjusting member A4.

The leaf A is provided with end-flcnges 3 which embrace the flanges l ofthe leaf A.

The spring A3 is provided at `one end with an arm l which projectsthrough the housing Q and bears against the outer surface of the leaf A.At the other end of the spring is a projection 5 which is received in arecess 6 with which the cup-shaped member A4 is provided in its bottomor end wall. The member A4 is provided circumferentially withperforations 7, any one of which is adapted to receive the reducedextremity of the stop-pin S, the outer end of which is adapted to bearagainst the outer surface of the leaf A.

Tension may be placed on the spring by rotating the cup-shaped memberA4. This may be done by means of a suitable implement, or by means of anail inserted through one of the openings 7. After rotating theSpecification of Letters Patent.

member A4 sufficiently to place the spring A3 under the desired tension,t-he stud or stop 8 is inserted and allowed to bear against the leaf A,as shown in the drawing.

The pintle A2 has its upper end provided with a head or flange 9 and itslower end is provided with a circumferential groove 10 affordingshoulders which adapt it to engage the upper and lower surfacerespectively of the lower flange 3 of the leaf A, as shown in Fig. 3.This engagement occurs automatically when the spring is placed undertension, the tendency being to force the lower end of the pintle to aneccentric position, as illustrated in Fig. 3.

In use, one leaf of the hinge is connected with the door-j amb, and theother with the l door. Then it is desired to disconnect the door, themember A4 may be rotated slightly by the use of an implement, the stud 8may then be withdrawn, and the member A4 may then be allowed -to rotateuntil the spring is no longer under tension. The pintle may then bereadily withdrawn.

By employing the hollow member A4, room is afforded for insertion of anail or implement, which may extend past thev pintle, so that a secureengagement of the imple-ment with the member A4 will be insured. It willbe noted that the groove 10 at the lower end of the pintle not onlyserves to prevent the pintle from working from its place, but alsoserves to strengthen the hinge by engagement with the lower flange 3.

A hinge of the construction described is simple, cheap and durable; sucha hinge is capable of being readily dismembered and enables adjustmentof the spring to any desired tension to be readily effected.

That I regard as new and desire to secure by Letters Patent isl. Aspring hinge comprising a leaf provided with end flanges and with aspring housing which is cut away adjacent one flange, a leaf providedwith end flanges embracing the end flanges of the first-named leaf, aspring in said housing having one extremity connected with one of saidleaves, a cup shaped, revoluble, springadjusting member confined betweensaid housing and the adjacent flange of said first-named leaf, saidspringadjusting member having its bottom portion connected with saidspring and having its circumferential port-ion provided with a series ofperforations, a stud adapted to engage said perforations, and a pintleextending through the flanges of said leaves, through the bottom of saidspringadjusting member and through said coilspring.

2. A spring hinge comprising a pair of leaves provided with upper andlower flanges, one of said leaves equipped with a. spring-housing, aspring in said housing and connected with one of said leaves, a

revoluble, spring-adjusting nienlher con-V of one of said leaves.
